使用 SSH 时转义引号

发布于 2024-11-18 22:56:41 字数 757 浏览 2 评论 0原文

我正在尝试为我的 PHP 应用程序构建一个简单的部署脚本。我知道有几种工具可以完成这项工作（Capistrano、Phing 等），但对于我的简单部署例程来说，它们似乎需要大量工作。

我使用 sshpass 来避免一遍又一遍地输入密码。但上传压缩安装程序后，我需要 ssh 进入服务器并运行一些命令。其中之一是 sed。所以，引号破坏了我的脚本。它是这样的：

sshpass -p foo ssh user@host "
   cd /www/htdocs/foo/bar 
   echo 'Untar and remove installer'
   tar -zxf install.tar.gz

   sed "s/define('ENVIRONMENT', 'development');/define('ENVIRONMENT', 'production');" index.php > tmp && mv tmp index.php
   sed "s/define('ENVIRONMENT', 'development');/define('ENVIRONMENT', 'production');/" admin/index.php > tmp && mv tmp admin/index.php

"

正如您所看到的，我使用双引号来开始我的 SSH 语句，但我也需要在 sed 上使用它们。

任何建议将不胜感激。谢谢！

I'm trying to build a simple deployment script for my PHP apps. I know there are several tools for this job (Capistrano, Phing, etc.) but they seem like a lot of work for my simple deployment routine.

I use sshpass to avoid typing my password over and over again. But after uploading my compressed installer, I need to ssh into the server and run some commands. One of which is sed. So, quotes are breaking my script. It's something like this:

sshpass -p foo ssh user@host "
   cd /www/htdocs/foo/bar 
   echo 'Untar and remove installer'
   tar -zxf install.tar.gz

   sed "s/define('ENVIRONMENT', 'development');/define('ENVIRONMENT', 'production');" index.php > tmp && mv tmp index.php
   sed "s/define('ENVIRONMENT', 'development');/define('ENVIRONMENT', 'production');/" admin/index.php > tmp && mv tmp admin/index.php

"

As you can see, I use double-quotes to start my SSH statements, but I also need to use them on sed.

Any suggestions would be greatly appreciated. Thanks!

转义内部引号是正常的方法。这不行吗？

sshpass -p foo ssh user@host "
cd /www/htdocs/foo/bar
echo 'Untar and remove installer'
tar -zxf install.tar.gz

sed \"s/define('ENVIRONMENT', 'development');/define('ENVIRONMENT', 'production');\" index.php > tmp && mv tmp index.php
sed \"s/define('ENVIRONMENT', 'development');/define('ENVIRONMENT', 'production');/\" admin/index.php > tmp && mv tmp admin/index.php

"

Escaping the internal quote marks is the normal way. Does this not work?

sshpass -p foo ssh user@host "
cd /www/htdocs/foo/bar
echo 'Untar and remove installer'
tar -zxf install.tar.gz

sed \"s/define('ENVIRONMENT', 'development');/define('ENVIRONMENT', 'production');\" index.php > tmp && mv tmp index.php
sed \"s/define('ENVIRONMENT', 'development');/define('ENVIRONMENT', 'production');/\" admin/index.php > tmp && mv tmp admin/index.php

"

可以使用此处文档代替吗？：

sshpass -p foo ssh user@host <<DATA
   cd /www/htdocs/foo/bar 
   echo 'Untar and remove installer'
   tar -zxf install.tar.gz

   sed "s/define('ENVIRONMENT', 'development');/define('ENVIRONMENT', 'production');" index.php > tmp && mv tmp index.php
   sed "s/define('ENVIRONMENT', 'development');/define('ENVIRONMENT', 'production');/" admin/index.php > tmp && mv tmp admin/index.php
DATA

Can a here-document be used instead?:

sshpass -p foo ssh user@host <<DATA
   cd /www/htdocs/foo/bar 
   echo 'Untar and remove installer'
   tar -zxf install.tar.gz

   sed "s/define('ENVIRONMENT', 'development');/define('ENVIRONMENT', 'production');" index.php > tmp && mv tmp index.php
   sed "s/define('ENVIRONMENT', 'development');/define('ENVIRONMENT', 'production');/" admin/index.php > tmp && mv tmp admin/index.php
DATA
